I realize this is a goof thread, but the one and only MARS mod I ever did was on my Alinco DX-SR9T. Never used a soldering iron before but the mod looked pretty easy. No de-soldering micro components. The mod involved adding a solder blob in between two pads then a reset. I figured I was going to turn my rig into a paper weight, but I dripped a nice blob of solder between the pads, let it cool, did a full reset and I was shocked to see that it worked and still works some 7 years later.
